| 3 | A new species of the genus Stygothrombium, representing a newly recorded superfamily Stygothrombioidea Mullen & Vercammen-Grandjean, 1980(Acari: Stygothrombiae) from China显示文摘The paper deals with a species new to science,Stygothrombium garzensis Li&Guo,sp.nov.,collected from Qinghai-Tibet Plateau,P.R.China,which represents a newly recorded superfamily Stygothrombioidea Mullen&Vercammen-Grandjean,1980 to Chinese fauna.The new species is described and illustrated in detail,especially the quantity and characteristic of idiosomal glandularia,with the diagnosis of infracapitulum base approximately 3.5 times as long as rostrum,the second pair of posterior setae on prodorsal plate about half length of posterior portion of prodorsal plate and the second ventroglandularia between the third acetabula and inner posterior angle of the fourth coxae,located at one-third of interval near the third acetabula approximately. | Haitao Li Daochao Jin Jianjun Guo | 2021 | Zoological Systematics2021，46，4： | 0 |
| 4 | Characterization and functional analysis of chitinase family genes involved in nymph-adult transition of Sogatella furcifera显示文摘Chitinase degrades chitin in the old epidermis or peritrophic matrix of insects,which ensures normal development and metamorphosis.In our previous work,we comprehensively studied the function of SfCht7 in Sogatella furcifera.However,the number and function of chitinase genes in S.furcifera remain unknown.Here,we identified 12 full-length chitinase transcripts from S.furcifera,which included nine chitinase(Cht),two imaginal disc growth factor(IDGF),and one endo-β-N-acetylglucosaminidase(ENGase)genes.Expression analysis results revealed that the expression levels of eight genes(SfCht3,SfCht5,SfCht6-1,SfCht6-2,SfCht7,SfCht8,SfCht10,and SfIDGF2)with similar transcript levels peaked prior to molting of each nymph and were highly expressed in the integument.Based on RNA interference(RNAi),description of the functions of each chitinase gene indicated that the silencing of SfCht5,SfCht10,and SfIDGF2 led to molting defects and lethality.RNAi inhibited the expressions of SfCht5,SfCht7,SfCht10,and SfIDGF2,which led to downregulated expressions of chitin synthase 1(SfCHS1,SfCHS1a,and SfCHS1b)and four chitin deacetylase genes(SfCDA1,SfCDA2,SfCDA3,and SfCDA4),and caused a change in the expression level of two trehalase genes(TRE1 and TRE2).Furthermore,silencing of SfCht7 induced a significant decrease in the expression levels of three wing development-related genes(SfWG,SfDpp,and SfHh).In conclusion,SfCht5,SfCht7,SfCht10,and SfIDGF2 play vital roles in nymph–adult transition and are involved in the regulation of chitin metabolism,and SfCht7 is also involved in wing development;therefore,these genes are potential targets for control of S.furcifera. | Xibin Yang Cao Zhou Guiyun Long Hong Yang Chen Chen Daochao Jin | 2021 | Insect Science2021，28，4： | 0 |
| 5 | Integrative approach of morphology and geometric morphometrics to species delimiation in Torrenticolidae(Acari:Hydrachnidiae)显示文摘This paper explores the integrative utilization of morphology and geometric morphometrics in order to deal with sibling species in Torrenticolidae. The results suggest:(1) Features of anterior margins of coxae, dorsoglandularia 1–4 and infracapitulum can be utilized in landmark-based geometric morphometrics approach;(2) A new species, Torrenticola brevisuturae Gu & Guo, sp. nov., is reported in this paper. | Xinyao Gu Haichuan Xiao Daochao Jin Jianjun Guo | 2022 | Zoological Systematics2022，47，2： | 0 |
| 6 | Two new species and two newly recorded species of Tenuialidae in China,with an updated key to the family(Acari:Oribatida:Gustavioidea)显示文摘In this work,two new species belonging to the family Tenuialidae from China are described:Tenuiala hubeiensis sp.nov.,Hafenrefferia eurycuspis sp.nov.Two species,Tenuiala nuda Ewing,1913 and Hafenrefferia gilvipes(Koch,1839),are reported for the first time in China.A key is provided for adult identification of the world known species of Tenuialidae.All examined specimens are deposited in the Institute of Entomology,Guizhou Universiy(GUGC),Guiyang,Guizhou. | Yan Zhang Daochao Jin | 2016 | Zoological Systematics2016，41，3： | 0 |
| 7 | A new species representing a new record genus Neoatractides from China(Acari: Hydrachnidia: Torrenticolidae)显示文摘A new species, Neoatractides(Heteratractides) proclusterosetus sp. nov., is described and illustrated in detail, which represents a new recorded genus Neoatractides Lundblad, 1941 and subgenus Heteratractides Lundblad, 1941 from China. The diagnosis of the subgenus Heteratractides is provided. The new species can be distinguished from other species by the dorsal shield consisting of two pairs of small dorsal platelets and a large dorsal plate.

| 8 | Occurrence Regularity of Major Damage Generations of Nilaparvata lugens(Stl) in Single Cropping Medium Rice Region in Sandu County of Guizhou Province显示文摘In order to clarify occurrence regularity of major damage generations of Nilaparvata lugens( Stl) in Sandu Shui Autonomous County( Sandu County for short),Guizhou Province,a karst single cropping medium rice region,the population dynamics of N. lugens were systematically studied using the methods of light trap and systematic field survey from 2009 to 2011. The results showed that the number of immigration generations caught by light trap and the actual population of N. lugens in fields were different among three years. The daily maximum trapping numbers of N. lugens amounted to 6 688 in 2009,which were 15. 3 and 2. 5 times of that in 2010 and 2011,respectively. The peak numbers in prediction nursery were 10 777,4 630 and 1 615 heads per hundred hills in 2009,2010 and 2011,respectively. The forth and fifth generations of N. lugens were the major damage generations in single cropping medium rice fields,and the initial immigration day was significantly related with primary-peak day. The occurrence degree of adults and nymphs of N. lugens varied with years and transplanting periods,and the peak days of N. lugens nymphs were from late July to early August in 2010 and 2011. The occurrence peaks of adults and nymphs in late transplanting paddy field were later than that in the early one. Meanwhile,the coexisted various growth periods of rice,due to time differences of transplanting,were conducive to inhabitation and reproduction of N. lugens. The population dynamics of spiders and Cyrtohinus lividipennis well synchronied with that of N. lugens,but predatory capacity of spiders and C. lividipennis was not enough to control N. lugens. | Liu Tianlei Jin Daochao Yang Hong Ai Zhengxian Zhou Zhaoxia | 2014 | Plant Diseases and Pests2014，5，2： | 0 |
